When the bin 13 stops feeding, the weighing value of the electronic platform scale 34 is the actual weighing value after a delay of 5 to 10 seconds. The static weighing method has high accuracy, and the impact of the material on the electronic platform scale 34 is considered. A shock-absorbing cushion is added above the sensor to reduce the impact of the falling material on the electronic platform scale 34 below, prolonging the service life. If the sensor is damaged, it can be replaced with a new sensor after calibration. Plug in the corresponding interface, which does not affect the operation of the entire weighing module. The sensor uses a METTLLER TOLEDO brand weighing sensor, and the specific parameters are as follows: model: MT1260-750kg, range: 0-750kg, sensitivity: 2±0.2mV, material: stainless steel, accuracy: OIML R60 C3, protection level: IP67.
